452272 ÷ 75 
The aim is to understand the frequency of 75 in 452272.

Advancing to step 1:
If we divide 4 by 75, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 75

Let's proceed to step 2:
If we divide 45 by 75, we get 0 and a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Grab the next digit (2) from the dividend, add it to 45, then carry on: 452 / 75

Advancing to step 3:
If we divide 452 by 75, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 450 from 452 and we're left with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 75

Step 4:
The number 75 fits into 22 0 times, leaving a remainder of 22.
The next digit of our result is 0. 
Result so far: 60.0
Deduct 0 from 22 and we're left with 22.
Bring next digit (7) of the dividend behind the 22 and repeat the process: 227 / 75

Step 5:
227 divided by 75 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 603.0
The remainder is 2 after subtracting 225 from 227.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 75

Let's proceed to step 6:
75 can be fit into 22 0 times, resulting in a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 6030.0
Subtract 0 from 22 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 7:
75 goes into 220 2 times with a remainder of 70.
The next digit of our result is 2. 
Result so far: 6030.2
If we take 150 away from 220, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
700 divided by 75 is 9 with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 6030.29
The remainder is 25 after subtracting 675 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
250 divided by 75 is 3 with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 6030.293
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 10:
If we divide 250 by 75, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 6030.2933
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 6030.2933, with a leftover of 0.00025.
